Topic: Pulleys and cruiseing RPM (Read 4592 times)

Looks like the belt has 133 teeth, 1-1/4" wide and 14 mm pitch. The pulley has 66 teeth. If a 60 tooth pulley were to be used, that's 6 less teeth or (.5 x 14 mm x 6) = 42mm (1.653"). The rear wheel would move back 42 mm. It doesn't look like there is that much adjustment. I estimate there are 8 mm (5/16") adjustment towards the rear.

I wouldn't waste time or money for a 120RPM drop at 80 and less at 60. That not going to even be noticeable.

With my 240 tire actually at 60 mph its dropping me 267 rpm and at 80 its dropping me 356 rpm. I cant say weather ill notice it yet because their just sittin on my work bench.Where are you getting 120 rpm at 80 at ??

I did about an equivalent change on my last bike (it was chain drive, I think I went from 59 teeth to 64 teeth). I loved it. 1st gear was noticeably slower, but it wasn't a torque monster like the Raider. On the highway it was soooo much nicer. I could cruise at 80 in comfort. Overall I think it made the bike much more pleasurable to ride, and gave me about 3-4 MPG at the same time.

Definitely let us know what you think of it. I'd be tempted, but my Raider is a city cruiser. If I want to do long hauls I'll buy a bagger.

I am hopeing it will help me out on my fuel stops and mainly stop me where i always try to hit that sixth gear all the time. I definitely will let ya know . If i dont like it itll come off If i had a decent camera i would put some pictures up being the new pullley is chrome . But one on the phone ant worth a crap.

This is something I have considered a couple times here and there. Is there anyone out there that does anything for a tooth up for the front pulley? 1 tooth increase should be nearly the same as the 61 tooth on the rear right? I know it REALLY tames a cr500r two-stroke and knocks a ton of R's off. Of course I haven't started looking yet, one of those future mods, just wondering if anyone had found anything. It is relegated to the future category because this winter my plast is plenty full of bike work. Might help somebody else though.

So, it's clear now. I want this mod. I dit it also for my previous VN800, changed front sprocket from 16 teeth to 18 teeth and loved the cruising speed.

Before to proceed I would go to the easiest way => Is there available a front sprocket with 33 or 34 teeth, which will match ? because the original belt can be used and the change will be only the front sprocket.

If not, means I have to change two things :

1. Belt, with 130T and 1 1/8 width. This is not an issue, just search into ebay.
